Presidential Hopeful Marco Rubio Already has a Tax Plan

3 min readBy: Kyle Pomerleau

Yesterday, Senator Marco Rubio (R-FL) announced his plans to run for the Presidency. One thing that sets him apart from the others that have announced so far is that he has a comparatively detailed taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. plan that he released with Senator Mike Lee (R-UT). One of the advantages of that is we can really analyze the effects of what a Rubio tax plan would have on the economy and taxpayers.

His tax plan would make quite a few changes to the current code, but it’s easy to think of it as having two pieces: business-side reforms and individual-side reforms.

On the business side, the tax plan fixes a lot of problems with the current code.

  • It reduces the corporate income taxA corporate income tax (CIT) is levied by federal and state governments on business profits. Many companies are not subject to the CIT because they are taxed as pass-through businesses, with income reportable under the individual income tax. rate (and the tax rate for pass-through businesses) to 25 percent.
  • Allows all businesses to fully deduct the cost of investments the year in which they incurred the expense.
  • Fully integrates the individual and corporate tax code to eliminate the double-taxation of corporate income.
  • Moves to a territorial tax systemA territorial tax system for corporations, as opposed to a worldwide tax system, excludes profits multinational companies earn in foreign countries from their domestic tax base. As part of the 2017 Tax Cuts and Jobs Act (TCJA), the United States shifted from worldwide taxation towards territorial taxation. that would exempt active foreign income of U.S. corporations from domestic taxation
  • Eliminates most business tax credits and many special deductions

On the individual side, the plan would cut taxes for just about everyone

  • Reduces the number of tax brackets to two (15 percent and 35 percent)
  • Eliminates nearly all itemized deductions
  • Creates a new $2,500 child tax creditA tax credit is a provision that reduces a taxpayer’s final tax bill, dollar-for-dollar. A tax credit differs from deductions and exemptions, which reduce taxable income, rather than the taxpayer’s tax bill directly.
  • Replaces the standard deductionThe standard deduction reduces a taxpayer’s taxable income by a set amount determined by the government. It was nearly doubled for all classes of filers by the 2017 Tax Cuts and Jobs Act (TCJA) as an incentive for taxpayers not to itemize deductions when filing their federal income taxes. and personal exemption with a fully refundable personal credit

The business side of the plan would greatly reduce the cost of capital, which would lead to much higher levels of investment. Thus, Rubio-Lee’s tax plan would net a 15 percent higher GDP in the long term. This would lead to a 12.5 percent increase in the wage rate and around 2.6 million more full time equivalent jobs.

On the individual side, all taxpayers, regardless of income level, would benefit from the tax plan. At the top end, the top marginal tax rateThe marginal tax rate is the amount of additional tax paid for every additional dollar earned as income. The average tax rate is the total tax paid divided by total income earned. A 10 percent marginal tax rate means that 10 cents of every next dollar earned would be taken as tax. would go from 39.6 percent to 35 percent, which would boost the after-tax incomeAfter-tax income is the net amount of income available to invest, save, or consume after federal, state, and withholding taxes have been applied—your disposable income. Companies and, to a lesser extent, individuals, make economic decisions in light of how they can best maximize their earnings. of the top 10 percent of earners by 10 percent. At the bottom end, the loss of the standard deduction, personal exemption, and 10 percent income tax bracketA tax bracket is the range of incomes taxed at given rates, which typically differ depending on filing status. In a progressive individual or corporate income tax system, rates rise as income increases. There are seven federal individual income tax brackets; the federal corporate income tax system is flat. is more than made up for with the new $2,000 refundable personal credit. For the lowest income earners, that would mean an increase in after-tax income of more than 40 percent.

While the plan promises a significant amount of economic growth and would net higher after-tax income for all taxpayers, someone still loses. In the case of this tax plan, the government ends up losing. The Rubio-Lee tax plan would greatly reduce the amount of tax revenue that the U.S. government will collect.

According to our analysis, the plan will cost $414 billion each year on a static basis, or more than $4 trillion over the next decade. Even if you assume that the plan results in a large amount of economic growth and thus a reflow of revenue from the large economy, the plan will still increase the debt by 8 percent in the next decade. Only after ten years would the plan start to net additional revenue each year. It would likely take over 25 years to start reducing the debt from its current point. This assumes that no other spending or tax policies change over this long period of time.
